CVE-2004-1158: Konqueror 3.x up to 3.2.2-6, and possibly other versions, allows remote attackers to spoof arbitrary web si...

Security readout for executives and security teams

This is an old Konqueror browser spoofing issue. A malicious site could make attacker-controlled content appear inside a window or tab associated with a trusted site, potentially fooling users during browsing. The main business risk is phishing or trust abuse on legacy Linux/KDE desktops still using affected Konqueror versions. Exposure is most likely on legacy systems with Konqueror 3.x or old KDE packages from affected Linux distributions. Modern managed endpoints are unlikely to be exposed unless historical browser packages remain installed or used. Treat as a legacy exposure cleanup item unless affected browsers are still in active use. Prioritize remediation for shared workstations, kiosk-like systems, or environments where users access sensitive web portals. Mitigation focus: Apply relevant KDE, Red Hat, or SUSE vendor security updates for affected Konqueror packages.; Retire Konqueror 3.x from managed endpoints where business use is not required.; Check vendor guidance if versions differ from those explicitly named in the CVE description..
